The characteristics and components of ripple depend on its source: there is single-phase half- and full-wave rectification, and three-phase half- and full-wave rectification.

Power supply output requirements usually specify a minimum DC voltage, an output voltage range or percentage of voltage regulation, ripple factor.

On the other hand, the ripple can be reduced by increasing the order of the filter while at the same time maintaining the same rate of roll-off.

A more common solution where good ripple rejection is required is to use a reservoir capacitor to reduce the ripple to something manageable and then pass the current through a voltage regulator circuit. The regulator circuit, as well as providing a stable output voltage, will incidentally filter out

Most power supplies are now switched mode designs. The filtering requirements for such power supplies are much easier to meet owing to the high frequency of the ripple waveform. The ripple frequency in switch-mode power supplies is not related to the line frequency, but is instead a multiple of the
